Bronze sculpture 'Lovebirds' by artistic duo Frans & Marja de Boer Lichtveld during 2000-2005. The couple used the cire perdue technique, with a unique sculpture as result. In this technique the wax is lost during the process of casting the bronze. At the top of the sculpture is signed: 'de boer lichtveld'. The artistic duo made additional to their individual work also collaborative work together from 1970 on. They made some big commissioned pieces domestically as well as abroad. Marja de Boer Lichtveld is still active as artist.
